Gross pay 948.45. Contribution = 0.05 * min(948.45, 4500) = 0.05 * 948.45 = 47.4225 → 47.42. Allowed deduction 1.03 ≤ min(400, 948.45 - 47.42 = 901.03) → OK. Taxable pay = 948.45 - 47.42 - 1.03 = 900.00. Tax: free 900. Taxable 900.00 → up to 900 untaxed. Portion above 900 up to 3300 at 8% = 0. Income tax = 0.00. Net pay = 948.45 - 47.42 - 1.03 - 0 = 900.00. Calculate with tool.

Compute: contribution = round(min(948.45, 4500)*0.05, 2) = round(47.4225,2)=47.42. Allowed deduction 1.03 ≤ 400 and ≤ 948.45-47.42=901.03. OK. Taxable = 948.45 - 47.42 - 1.03 = 900.00. Tax: free 900 → taxable 900.00 is exactly at free amount → tax = 0.00. Net = 948.45 - 47.42 - 1.03 - 0 = 900.00. Use calculate.

Reasoning
Note R2 says "Do not round intermediate bracket products separately before summing income tax." My approach rounded bracket products separately. But here both are zero so total is the same. However for correctness of my own computation, it doesn't matter. Actually let me verify: tax = (min(900,3300)-900)*0.08 + max(0,900-3300)*0.18 = 0 + 0 = 0. Fine. Output JSON with clauses R1-R6.
